推荐答案

  String charset = "ISO-8859-1"; // or what corresponds
  BufferedReader in = new BufferedReader( 
      new InputStreamReader (new FileInputStream(file), charset));
  String line;
  while( (line = in.readLine()) != null) { 
    ....
  }

你有解码的文字。您可以使用simmetric Writer / OutputStream方法，使用您喜欢的编码（例如UTF-8）来编写它。

There you have the text decoded. You can write it, by the simmetric Writer/OutputStream methods, with the encoding you prefer (eg UTF-8).
